Blumpkinetics 

The study of the physics involved in giving and receiving blumpkins. This field includes such concepts as oral/anal viscosity and drag analysis, Navier-Stokes Fluid computations, and statistical fecal scattering modeling.

I just completed my Masters of Blumpkinetics at Brown University.
